Patent GB-2136815-A (GB)
Title: Broad spectrum plant protection from pathogens
Inventor: CARTER WILLIAM ALVIN
IPC: A01N63/60
Filed: 1983-08-04
Abstract: Methods for protecting plants against viral attack comprising causing the plants to generate an ancestral interferon response to the virus. The response can be generated by genetically altering the plant to contain ancestral interferon genetic information as embodied typically in human interferon so that the plant produces its own interferon, or by topically applying animal interferon, including human intracellular mediators, or interferon inducers such as dsRNAs. Less-than-entire interferon molecules will work so long as, e.g. a fragment contains an essential amino acid sequence which is independently capable of inducing the interferon response.

Abstract: An optical fiber tap which is especially useful as a node in a local area network, especially a ring topology local area network. The tap, which does not interrupt the physical continuity of the fiber, has an open position and a closed position. In the open position, a signal passing down the optical fiber (14, 122) passes through the tap without alteration. In the closed position, a signal passing down the optical fiber is extracted through a first bend (16) which is put into the fiber by the tap; the extracted signal, or an electrical counterpart thereof, is processed and a counterpart of the extracted signal, or a new signal obtained by operating on the extracted signal, e.g. in a data processor, is injected into the fiber through a second bend (24) which is put into the fiber by the tap. The tap may also contain an attenuator (32) between the signal extractor and injector, so that only that signal injected by the tap propagates down the fiber beyond the tap.
Patent GB-2143944-A (GB)
Title: Inspection of printed wiring boards
Inventor: DOYLE KEITH GILBERT
IPC: G06T7/00
Filed: 1984-07-20
Abstract: A printed wiring board is tested by optically scanning in two orthogonal, X-Y axes such that for each scan in the Y direction a narrow strip of the board of predetermined width, W in the X direction is arranged to provide n.m discrete pixel signals, wherein n is a predetermined number of pixels across the width W of the strip (typically 1000) and m is a number of pixels along the board in the Y direction. The signals are processed in groups of n X m or smaller. Control means is arranged to cause the scanning means repeatedly to scan the board in the Y direction and to step it a predetermined amount in the X direction at the end of each scan until a required area of the board has been scanned and the processing means has processed a plurality of said groups of signals to indicate where the width of the track or the spacing between the track is too small, and to identify common areas of each conductive track. At the completion of a test, there is stored information representative of the X-Y coordinates of a plurality of datum areas, e.g. holes and edge connectors, and of the said datum areas which are interconnected by satisfactory track, which may be compared with the wiring list for a correct board. <IMAGE>

Title: A load-responsive brake pressure regulator for vehicles
Inventor: GILLES LEO
IPC: B60T8/18
Filed: 1984-08-16
Abstract: An inlet chamber (14) adapted to be connected to a brake master cylinder and an outlet chamber (44) adapted to be connected to at least one wheel brake cylinder are each defined by a respective stepped piston (18 and 48). One or each stepped piston (18, 48) is supported by an adjustment member (72) which is adjustable in response to the loading of the vehicle. The larger diameter areas (26, 56) of both stepped pistons (18, 48) define spaces which constantly communicate with each other and are connected to the inlet chamber (14) by a pressure reducing valve (34) and to the outlet chamber (44) by the pressure increasing valve (64) disposed in one each of the two stepped pistons (18,48) up to a pressure only which depends on the adjustment of the adjustment member (72). The combined effect of both stepped pistons (18, 48) and the associated valves (34, 64) permits the course of the pressure in the outlet chamber (44) as compared to the pressure in the inlet chamber (14) to be adapted largely to the ideal course of pressure which depends on the loading condition of the vehicle. The pistons and valves may be arranged in parallel bores (Figure 1 not shown). <IMAGE>
